change camshaft sensor and crankshaft sensor but still have the same problem on 2004 Infiniti G35

when I put the car in gear and release clutch the car goes no where

Asked by for the 2004 Infiniti G35
does it stay RUNNING? Why did you replace the sensors?
Because the car was take long to move and service engine light came on I put it on the diagnostic system and it gave me PO175 AND PO340 code and yes it stay running
You mentioned the word 'clutch'...........and car not moving many miles on it and has the clutch ever been replaced?
